We demonstrate a new imaging technique for velocity measurements in particle-laden flows. The technique, particle vaporization velocimetry, is a form of flow tagging based on laser vaporization of absorbing particles at defined locations in the flow.

This study aims to improve a technique for measuring fuel distributions, e.g. mixture fraction and droplet sizes, in evaporating and mixing (two-phase) fuel sprays. The technique is based on planar laserinduced fluorescence of acetone, used as a surr

Laser-induced incandescence from soot was analyzed with a time-dependent, numerical model of particle heating and cooling processes that includes spatial and temporal intensity profiles associated with laser sheet illumination. For volume fraction me

We used a time-dependent, numerical model of the soot particle heating and cooling processes to calculate signals from laser-induced incandescence (LII). Various laser sources were studied in order to compare their suitability for measurements of soo
